Spotted in Czech Republic. Our office was hit with cockroach infestation, so I'm afraid if I haven't carried one home.

    $\begingroup$ From my experiments with cockroaches as a kid (and crickets, mouses. frogs, ants, gecko's) this cilinder definately reminds me of their egg sac. (English is not my primary language, forgive any mistakes) $\endgroup$ Commented Dec 2, 2016 at 14:42

It is German cockroach (Blattella germanica) with two dark parallel streaks on it's pronotum.

The one in your picture is a lady laying her ootheca.

It is a pest.

Here's it in different stages of life cycle.

Things you might like to know:

Blattella germanica occurs widely in human buildings, but is particularly associated with restaurants, food processing facilities, hotels, and institutional establishments such as nursing homes.

German cockroaches are omnivorous scavengers. They are attracted particularly to meats, starches, sugars, and fatty foods. Where a shortage of foodstuffs exists, they may eat household items such as soap, glue, and toothpaste.

The German cockroach reproduces faster than any other residential cockroach, growing from egg to reproductive adult in approximately 50 – 60 days.
